In 2008, LandGlass introduced the combined flat glass tempering machine to meet the increasing quality requirements for tempered glass in the architectural and household appliances markets. The LandGlass combined tempering machine has two heating furnaces that can be controlled individually. The result is a significant quality increase that overpasses the glass quality requirements of the market.

AirStreamTM Radiation Heating plays a supportive role during the process. Compressed air is injected into the heating furnace to aid the heating process of the top surface of the glass, which ensures heating uniformity for on-line Low-E glass, and other glass types.

JetConvection PlusTM Convection heating plays an important role during glass heating. Air is heated in the JetConvection chamber inside the heating furnace and is blown onto the glass surfaces. Air is then recirculated and recirculated by the convection blowers into the JetConvection chamber. LandGlass Jetconvection technology enhances the quality of the final product and increases productivity by ensuring an even heating, while minimizing production costs.

LD-AT Series Combined Flat Tempering Machine is equipped with 2 heating sections, which can be installed with either AirStream or JetConvection heating technologies. The furnace can also be equipped with one or more chillers according to the quality and productivity requirements of the final product. The combination of 2 heating sections allows for an easy adaptation to each customer's needs, having the possibility to select different working modes that optimize final quality, productivity or maximum temperable size.

Productivity is calculated on 5mm clear glass and 6 mm Low-E glass (E=0.08) with 65% loadage. Actual productivity is subject to glass types, sizes and loadage. Not all types are listed here due to limited space.
